In exchange for performing these services, WMMRC pays such service provider a management fee. WMIH entered into an Investment Management Agreement and an Administrative Services Agreement with WMMRC on March 19, 2012.

These agreements are described below. Under the terms of such Investment Management Agreement, WMIH receives from WMMRC a fee equal to the product of (x) the ending dollar amount of assets under management during the calendar month in question and (y) .002 divided by 12. WMIH is responsible for investing the funds of WMMRC based on applicable investment criteria and subject to rules and regulations to which WMMRC is subject. Under the terms of such Administrative Services Agreement, WMIH receives from WMMRC a fee of $110 thousand per month. WMIH is responsible for providing administrative services to support, among other things, supervision, governance, financial administration and reporting, risk management, and claims management as may be necessary, together with such other general or specific administrative services that may be reasonably required or requested by WMMRC in the ordinary course of its business. On March 22, 2012, WMIH and the WMI Liquidating Trust (the “Trust”) entered into a Transition Services Agreement (the “TSA”). Pursuant to the TSA, the Trust makes available certain services and employees, including the services of our Chief Legal Officer and Secretary and our Controller. The TSA provides the Company with basic infrastructure and support services to facilitate the Company’s operations. The TSA, as amended, extends the term of the agreement through June 30, 2018, with automatic renewals thereafter for successive additional three-month terms, subject to non-renewal at the end of any additional term upon written notice by either party at least 30 days prior to the expiration of the additional term. On or about October 14, 2014, the Trust filed a lawsuit in King County Superior Court in the State of Washington against 16 former directors and officers of WMI (the “D&O Litigation”). The Trust’s complaint alleged, among other things, that the defendants named therein breached their fiduciary duties to WMI and committed corporate waste and fraud by squandering WMI’s financial resources. In connection with the settlement of the D&O Litigation, during the year ended December 31, 2015, among the Trust, certain former directors and officers of WMI and certain insurance carriers that underwrote director and officer liability insurance policies for the benefit of WMI and its affiliates (including such former directors and officers), such insurance carriers agreed to pay the Trust $37.0 million, of which $3.0 million was placed into a segregated reserve account (the “RSA Reserve”) to be administered by a third party pursuant to the terms of a Reserve Settlement Agreement (the “RSA”). Based on elections of certain holders of claims in connection with our bankruptcy prior to the Effective Date, WMIH retained an economic interest in certain litigation proceeds, if any, recovered by the Trust, including those related to the D&O Litigation. During the year ended December 31, 2017, 2016 and 2015, WMIH had other income of $123 thousand, $123 thousand and $7.8 million, respectively, as a result of its receipt of its share of net litigation proceeds related to the D&O Litigation. As of December 31, 2017, $1.5 million remained in the RSA Reserve. Under the RSA, funds are released from the RSA Reserve to the Trust if and when certain designated conditions are satisfied. If and when these funds are released to the Trust, and to the extent WMIH is entitled to receive such funds, it is anticipated the Trust will make payments to WMIH in an amount equal to WMIH’s share of litigation proceeds. Due to the contingent nature of future distributions from the RSA Reserve, there can be no assurance that WMIH will receive any distributions from the remaining balance in the RSA Reserve in the future. In preparation for the offering of the Original Series B Preferred Stock, WMIH engaged KKR Capital Markets LLC (“KCM”), an affiliate of KKR & Co. L.P., to act as a joint book-running manager for the Series B Preferred Stock offering. KCM also acted as an initial purchaser of the Original Series B Preferred Stock. During the year ended December 31, 2015, as a result of satisfying a post-closing covenant to reincorporate in the State of Delaware within 180 days following the closing of the Original Series B Preferred Stock offering, we paid $8.25 million to KCM. Upon consummation of a “Qualified Acquisition” (as such term is defined in Article VI of WMIH’s 2nd Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”)), we will pay KCM an additional fee (the “KCM Deferred Fee”) of $8.25 million. We have recorded the KCM Deferred Fee in “other liabilities” on our consolidated balance sheet and this amount is included in “accrued fees relating to Series B Preferred Stock issuance” on our consolidated statements of cash flows.
